Actually I'd like to remove it as well, since it still requires us to climb the tree to get the base URI while its only usage can be done in a much more efficient way. Actually I've filed a bug and been working on removing it. [1] Is there any reason you think we should keep the Get/SetExplicitBaseURI API?
